Ichneumons thus serve as another example of the diversity and balance of living things that man has yet to comprehend fully.

Although one may describe this insect group as ruthless parasites, ichneumon wasps serve an important purpose. Their larvae feed on insects that are harmful to food crops, including chinch bugs, boll weevils, codling moths, and asparagus beetles, to name a few. So ichneumons evidently control the proliferation of agricultural pests.
Evidently, the wt has all the answers, even when "man" doesn't. And the difficult cases, such as ichneumons preying on spiders that also help control insects, are simply disregarded.
